THE EXTRATERRESTRIAL REGOLITH ANALYZER (XTRA) WILL PROVIDE QUANTITATIVE MINERALOGY AND ELEMENTAL COMPOSITION OF AS-RECEIVED LUNAR SOIL. XTRA IS SUITABLE FOR A SMALL LUNAR LANDER OR ROVER BUT VARIANTS OF XTRA COULD BE USED BY ASTRONAUTS IN A LUNAR HABITAT AS WELL. THE WORK PROPOSED HERE BUILDS ON A NUMBER OF PREVIOUSLY FUNDED TECHNOLOGY DEVELOPMENT EFFORTS AS WELL AS HERITAGE FROM FLIGHT HARDWARE. XTRA WILL BE AT TRL-4 ON ENTRY INTO THE DALI PROGRAM. THE PROPOSED DALI EFFORT INCLUDES A DETAILED TECHNICAL APPROACH AND WORK PLAN TO ADDRESS IDENTIFIED TECHNOLOGY AND DESIGN RISKS TO FURTHER DEVELOP XTRA TO TRL-6 AT WHICH POINT IT WILL BE READY TO BE PROPOSED FOR A FLIGHT MISSION.
